Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

Chrysler defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.

Jeep Renegade gets Riptide and Frostbite customs at SEMA

The cute little Jeep Renegade isn't even on sale yet, but here at SEMA, the Mopar folks are giving us a taste of what's possible for the little CUV in the big wide world of customization. Part of Fiat Chrysler Automobiles' massive SEMA spread, the Renegade shows up in fresh Riptide and and Frostbite guises.
First up, the Riptide arrives in Vibrance Grandeur Blue with black wheels and a big ol' Jeep Performance Parts logo on the rear pillar. There are a few black accents elsewhere on the exterior, and a surfboard carrier rides up on the roof. The blue color scheme also finds its way inside the Renegade, on the instrument cluster and side panels, with contrasting white accents.
By contrast, the Frostbite Renegade reverses the Riptide's color scheme, with white being the main paint of choice, with blue accents abound. And inside, Katzkin seats wear blue upholstery. The Frostbite is a pretty functional creation, as well, with a Mopar ski/snowboard roof rack and a Jeep Performance Parts rock rail guard.
